CARPET-FASTENING.

SPECIFICATION forming part of vLetters Patent No. 761,467, dated May yApplication led March 5, 1904. vSerial No. 196,716. .(No model.)

To a/Z whom, t may concern:

Beit known that I, DANIEL T. FOLEY, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Carpet-Fastenings, of which the followingis a specification. Y

My invention consists of a carpet-fastening formed Aof a-doubly-threaded screw one end of which is adapted to be screwed into the riser of a stair or .the floor of an apartment and a head Vadapted to be fitted on the exterior threads of said screw and tighten and control the carpet, the outer end of the screw being adapted for the application of a screw-driver or other tool thereto for rotating the screw, said endappearing at the exterior of'said head, so as to be accessible without removal of the latter and. said end not limiting the tight-` ening action of said head.

It also consists of a prong adapted to cover the outer end of the screw and permit the carpet -to bepiercedby the same prior to its location on said screw.

Figure lrepresent's a front view of a fastening for stair-carpet embodying my invention. Fig. 2 represents a vertical section thereof 'on line Fig. 1. Fig. 3 represents a section of a prong which is vtted over the exterior portion of the screw as a sheath, so as to admit of the passage of the carpet over the blunt end of the screw. Fig. represents a plan view of a floor-carpet fastening embodying my invention.

Similar letters of reference indicate corresponding parts in the figures.

Referring to the drawings, A designates a I screw which has at one portion the thread B,

by which it may be screwed into the wood of a stairs or floor, and on the other portion the thread C, on which may be screwed or fitted the head D, which 'is interiorly threaded after the manner of a nut. The outer end of the screw is blunt and has formed therein the nick E for the engagement of a screw-driver or other tool, so as to drive the screw Into positlon, adjust the same, and rel move it when so required.

be fitted over the exterior portion of the screw A and cover the blunt end of the latter, whereby the carpet may be pierced by the same in its location on the stud.

VrIhe operation is as follows: The-screws are driven into the risers at opposite ends thereof. Prongs are placed on the exposed ends of said screws and the stair-carpet presented to said prongs and forced over and pierced by the same, so as to be slipped upon the screws, said prongs then being removed. The stairrod H is then applied over the screws, and the heads D are itted on the screws and tightenedagainst said rod, whereby the carments without removing the heads D, yand the i latter may be most firmly tightened vagainst the stair-rod without being controlled by the outer ends of the screws, the openings in said heads extending entirely through the same.

When it is desired to fasten Hoor-carpets, screws such as the above are driven into a ioor, the prongs are applied, and the carpet pressed over, said prongs, after which the latter are removed and the heads fitted on the projecting portions of 4the screws and tightened, said heads pressing against the washers J, as in Fig. 4, said washers in this case be'- ing somewhat of the form of rosettes or other ornamental shape and being substituted for the stair-rods of the otherliigures.

Various changes may be made in the details of construction shown without departing from the general spirit of my invention, and I do not, therefore, desire to be limited in each case to the same.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In a carpet-fastening, a screw having its outer end blunt and a nickin said end, and a head having an interiorly-threaded opening adapted to engage the outer portion of said screw, said opening extending entirely through said head and said nick appearing through Said opening.

2. In a carpet-fastening, a screw having a IOO blunt head, a sleeve adapted to be removably adapted to be tted on said projecting` portted over said head, and a piercing-point tion, a prong` adapted to be removably tted IO carried by Said sleeve on the outer end thereof. on said portion and cover said blunt end.

3. In a earpet-fastenino eonsistino of a n 1 f 5Serew adapted to be drivben into a sbtair or DANIEL l' FOLI floor and having a threaded portion projeet- Witnesses: ving outside of the latter, the outer end of said JOHN A. WIEDERSHEIM,

screw being blunt, and. a threaded head WM. CANER WIEDERSEIM.
